Yosemite: Its Wonders and Its Beauties (1868) by John S. Hittell

POMPOMPASUS.

A mile and a half beyond Tutucanula, on the same
side, is Pompompasus, or the Three Brothers, three
peaks in close proximity. The Indian name means
“mountains playing leap-frog,” and a sight of the
peaks shows the appropriateness of the title. The
highest of these is nearly 4,000 feet above the valley,
and from its summit, according to Mr. King of the
State Geological Survey, the finest view can be had of
the great chasm and of the surrounding scenery.
Other observers, however, who have remained longer
in the valley, and have looked upon it from more points,
think the view from Glacial Rock better. The ascent
of Pompompasus is difficult.
